The Prince of Wales in military hats on September 22 to present a new Guidon to The Queen’s own Yeomanry and this morning to present medals to members of The Royal Regiment of Scotland’s Black Watch 3rd Battalion.

The Duchess of Cambridge atttended her friend Sophie Carter’s wedding last weekend in a cornflower blue silk flower and crin bandeau headpiece from Juliette Botterill. It’s such a pretty colour but the combination of this design with the matching dress and coat reads too twee for my liking.

Princess Hisako and Crown Princess Masako both wore hats in fresh green hues this week- Princess Hisako officially closed the 7th Special Olympics National Summer Games in Aichi on Wednesday in this cream hat with green hatband and starburst bow while Crown Princess Masako wore this pistachio green bowler with brocade hatband on Thursday at the World Social Science Forum in Fukuoka.

Princess Camilla of Bourbon-Two Sicilies brought her daughters to a Fashion 4 Development event in New York. Her younger daughter, Princess Chiara, sported a red feathered fascinator.

Much has been written about the Duchess of Sussex’s first charity project in support of the Hubb Community Kitchen. Take time to read the cookbook’s forward (see it here)– clearly written in her own voice, it’s compelling and beautiful.

We end the week with my favourite royal photo of the week, taken yesterday in Scotland when the Duchess of Rothsay (as is her Scottish title) visited the cancer support charity Maggie’s Centers. So sweet.

Prince Joachim and Princess Marie visited to the army school Haerens Sergentskole in Varde on Tuesday. Joachim graduated from the school 30 years ago and his eldestson, Prince Nicolai (second from the right, below), enrolled in the school earlier this month.

Queen Margrethe was all smiles on Thursday at her French home, Chateau de Caix, where she welcomed journalists for an annual interview and photocall. This home was well known to be Prince Henrik’s escape and a personal favourite of the couple- as such, these photos on the first summer following his passing feel particularly poignant.

And from London milliner Edwina Ibbotson, the springiest of spring statement picture hats. I can only imagine this piece (and this vibrant rainbow design by the same designer) are already reserved for Ascot!

And the most stunning blue leather pillbox percher with hand beaded leaf trim by Dutch milliner Wies Mauduit (a familiar commenter here on Royal Hats!). The leaves are beautifully constructed and their placement is absolutely perfect on this hat (check out her (also check out her exquisite picture hats). Wies- your stunning designs deserve to be worn on royal heads!
